PUMP.

SPECIFICATION forming part of Letters Patent No. 370,666, datedSeptember 27, 1887.

Application filed February 28, 1887. Serial No. 229,146. (No model.)

To all whom it may concern:-

Be it known that I, DANIELL. VOLKER, of the city of Buffalo, in thecounty of Erie and State of New York, have invented a new and usefulImprovement in Pumps, of which the following is a specification.

This invention relates to that class of pumps in which the pump pistonor plunger works in a horizontal cylinder which is seated midway tobetween its ends in a vertical partition secured in the pump'casing. Thehorizontal cylinders of this class of pumps are liable to Work loose andget out of line.

The object of my invention is to securely [5 hold the horizontalcylinder in the pump-casing and to render the pump more convenient andserviceable in other respects; and my invention consists of theimprovements which will be hereinafter fully set forth, and pointed outin the claim. In the accompanying drawings, Figure l is a sectionalelevation of apump provided with my improvements. Fig. 2 is a verticalsection of the rear end of the pump-cylinder and its supporting sleeve.Fig. 3 is an end elevation thereof. Fig. 4 is a perspective viewthereof.

Like letters of reference refer to like parts in the several figures.

A represents the steam-cylinder, of ordinary construction; a, the pistonrod; and B the pump piston or plunger secured thereto. 0 is thehorizontal pump-cylinder in which the plunger B works, and which is openat both ends. D represents the pump-casing, and d the vertical partitionformed in the same and supporting the cylinder 0, the latter beingprovided with an external collar, e, which bears against the rear sideof the partition d. All of these parts are old and well known.

F represents the head at the rear end of the pump-casing; and Grepresents a sleeve, which is seated in an opening in the head F andprojects inwardly therefrom, so as to surround with its innerannular'portion, g, the rear portion of the pump-cylinder O. Thesleeve Gis secured to the head F by screws or bolts h, passing through ears h onthe sleeve.

I represents lugs formed on the inner side of the sleeve G, and t areset-screws arranged in said lugs and bearing with their inner endsagainst the rear end of the cylinder 0 and pressing the collar 6 of thelatter firmly against the partition d.

j represents'an annular row of openings or passages formed in the sleeveG, outside of the 35 inner annular portion, g, thereof, for the passageof the liquid into and from the rear end of the cylinder 0. The sleeveGsupports the rear end of the cylinder G, which latter is in this mannerprovided with two supports, whereby it is securely held in position inthe pump-casing and prevented from working out of line. The outer end ofthe sleeve G is covered by a cap, k, which is secured to the head F ofthe pump casing. Upon removing the cover It the plunger B can bewithdrawn without disturbing the sleeve G. Upon removing the latter thepump-cylinder O can be withdrawn. When the lower portion of the cylinder0 becomes Worn, the cylinder can be 0 turned in the partition to presenta fresh surface to the most intense action of the plunger.

I claim as my invention The combination, with the pumpcasing providedwith a partition, (1, of a pump-cylin- 5 der supported in said partitionand provided with a collar, 6, a sleeve, G, secured to the end of thepump-casing and provided with a ring, 9, which surrounds the end of thepumpcylinder and with internal lugs, I, and set screws z, working insaidlugs and bearing against the end of the pump-cylinder, substantiallyas set forth.

Witness my hand this 16th day of February, 1887.
